Help! After getting a flat tire fixed at a tire shop in Mexico I noticed a large scratch on the wheel. Does anyone know if MB or anyone else sells touch up paint for wheels? The wheels on my care are the standard 17' silver wheels that came with the car. Thank you.

 

For those wheels, use Mercedes Benz #9744 "brillantsilber metallic". (That's exactly how it's spelled on the touch up bottle!)
They will probably sell you a "kit" at the MB parts dept., which has that color and a small bottle of clear to go over the touch up.
The name on the clear says, "Klarlack".
I know you guys think I'm making this stuff up. I'm not. Must be a German thing. Obviously, clear lacquer.
That color should match your factory silver wheels. Does mine. Hope this helps.
